import * as cdk from 'aws-cdk-lib';
import { aws_batch as batch } from 'aws-cdk-lib';

declare const parameters: any;
declare const retryStrategy: batch.RetryStrategy;
const jobDefinitionProps: batch.JobDefinitionProps = {
  jobDefinitionName: 'jobDefinitionName',
  parameters: {
    parametersKey: parameters,
  },
  retryAttempts: 123,
  retryStrategies: [retryStrategy],
  schedulingPriority: 123,
  skipDeregisterOnUpdate: false,
  timeout: cdk.Duration.minutes(30),
};
```

## Properties

- `jobDefinitionName`: string — The name of this job definition.

  **Default:** generated by CloudFormation

- `parameters`: { [key: string]: any } = none — The default parameters passed to the container These parameters can be referenced in the `command` that you give to the container.

- `retryAttempts`: number = 1 — The number of times to retry a job.

  The job is retried on failure the same number of attempts as the value.

- `retryStrategies`: [RetryStrategy](/cdk/api/v2/docs/aws-cdk-lib.aws_batch.RetryStrategy.html)[] — Defines the retry behavior for this job.

  **Default:** no `RetryStrategy`

- `schedulingPriority`: number = none — The priority of this Job.

  Only used in Fairshare Scheduling
  to decide which job to run first when there are multiple jobs
  with the same share identifier.

- `skipDeregisterOnUpdate`: boolean — Specifies whether the previous revision of the job definition is retained in an active status after UPDATE events for the resource.

  **Default:** undefined - AWS Batch default is false

  When the property is set to false, the previous revision of the job definition is de-registered after a new revision is created.
  When the property is set to true, the previous revision of the job definition is not de-registered.

- `timeout`: [Duration](/cdk/api/v2/docs/aws-cdk-lib.Duration.html) — The timeout time for jobs that are submitted with this job definition.

  **Default:** no timeout

  After the amount of time you specify passes,
  Batch terminates your jobs if they aren't finished.
